Stochastic Cation Dynamics in Photovoltaic Hybrid Perovskites under Pressure
Methylammonium lead iodide (MAPI) is one the most promising materials for photovoltaics. Notwithstanding the above, access to its phase diagram and the underlying structural... -
Determining the interaction between water and carbon dioxide in smectite clay...
Interactions between CO2 and clay minerals have attracted interest in the scientific community recently. This is partly motivated by the presence of large amounts of clays in... -
Dynamics of Ethylene Glycol based Deep Eutectic Solvents: Effect of Cations
Deep eutectic solvents (DES) formed from a mixture of hydrogen-bond donors and metal salts, is a novel variety of solvents that have been synthesized and studied extensively. In... -
Comparison of Dynamical Behaviour in MAPbX3 and FAPbX3: How Do They Differ ?
Organic-inorganic lead halide perovskite compounds are shown to be very promising candidates for low cost, solution-processable, highly efficient (>22%) solar cells with a... -
Investigating the magnetic structure of the solid solution PrCr(1-x)MnxO3
Rare-earth (A= La, Ce, Nd, Pr) orthochromites (A CrO3) and orthomanganites (A MnO3) are of interest due to the number of unusual physical properties they possess, displaying... -
Quenched salt hydrates new ways of probing water clusters.
Very rapid quenching of liquids to form a glass, from which crystalline phases are subsequently obtained by devitrification, is a powerful technique for obtaining novel... -
High pressure behaviour of ammonium carbonate monohydrate
A number of compounds crystallise in the NH3-H2O-CO2 ternary system, including ammonium carbonates and carbamates, these being closely related to the water-deficient compound... -
Magnetic Fluctuations in BaCo2As2
ACo2As2 (A=Ba, Sr, Ca) are end members of Co doped Ba-122 family. Understanding the magnetic behavior of these end members can help us to understand the magnetic properties of... -
Incommensurate-commensurate phase transitions in K2SeO4
Materials with incommensurate structures often show exotic properties (such as charge density waves). The development of reliable and efficient refinement techniques for such... -
Phase Diagram of Ba1-xKxFe2As2
In the new class of iron pnictide superconductors, there is evidence of phase coexistence close to the phase boundary between the SDW and superconducting order produced by hole... -
The search for long range exchange interactions in the S=1 square lattice ant...
Exchange interactions in insulators can be understood in terms of the Andersen exchange picture in which the Hamiltonian has two contributions: (i) a kinetic term characterized... -
Structural and Magnetic Properties from Charge Orders in Iron Perovskite Oxides
Highly oxidized transition metal cations in oxides tend to display unusual electronic and magnetic behavior due to the highly covalent nature of the M-O interactions. Iron is of... -
Corona Dynamics in Polymer Stabilised Nanocomposites
The Payne effect, whereby filled polymers experience a loss of modulus under applied strain is responsible for much of the energy loss of vehicle tyres in everyday use. It has... -
